Rubric-Based AI Evaluation
Pilot-scoped service · Absolute scoring · English / Arabic
Absolute scoring of model responses on anchored, multi-dimension rubrics — the same response scored the same way, every time.
What it is
Scores with anchors, not vibes.
Where pairwise ranking answers “which is better,” rubric-based evaluation answers “how good is this, and on what dimensions.” We score each response against a rubric with defined dimensions and anchored scales — each scale point illustrated with examples — so scores mean the same thing across raters and across weeks.
Rubric design is the hard part, and it is where most evaluations fail: poorly anchored scales produce noise. We co-design the rubric with you, calibrate raters on it, and revise the anchors where calibration shows genuine divergence — before production scoring.
Deliverables
What you receive
- Scored evaluations with per-dimension rationales, in CSV or JSONL
- The anchored rubric — versioned, with scale examples
- Inter-rater reliability report and adjudication log
- QA report and acceptance review against criteria agreed up front
Process
How a pilot works
Rubric co-design
Dimensions, scale anchors, and worked examples — drafted with you and agreed in writing.
Rater qualification
Raters qualify against scored evaluations on your rubric.
Calibration
Double-scored calibration batch; anchors revised where raters genuinely diverge.
Production scoring
Production evaluations with reviewer sampling and reliability tracking.
Delivery and acceptance
Scores, rationales, and reliability report delivered for your acceptance review.
Scope and limits
What this service does not include — stated up front, so there are no surprises in scoping:
- Rubric quality bounds result quality — if a dimension can’t be anchored, we say so before scoring.
- English and Arabic only; no regulated data.
- No guaranteed accuracy figures; acceptance criteria are agreed per pilot.
